The Earth’s north magnetic pole has been moving from its old location in Northern Canada towards Siberia. And there is a growing concern among scientists that the weakening of the Earth’s magnetic field could someday cause its north and south poles to flip. And that could lead to global chaos.
The Earth’s magnetic north has been moving ever since it was first discovered in 1831. It’s driven by molten iron moving deep beneath the Earth’s crust.
But now magnetic north is moving so quickly that it forced the world’s geomagnetism experts to update the World Magnetic Model a year early.
That model is the basis for modern navigation, for ships and planes, satellites and smartphones, and it helps birds and other animals to navigate as well.
If Earth’s magnetic field were to decay significantly, scientists say it could collapse altogether and flip polarity – changing magnetic north to south and south to north. The planet’s magnetic poles are believed to have flipped before in earth history, but never in a time with such a dependence on technology.
And many scientists now say a flip of north and south is looking more and more certain.
Dr. Hugh Ross said, “These reversals we’ve been hearing about – they have happened several hundred times in the past half-billion years of earth’s history. And we already have a pretty good idea of what’s going to happen during a reversal. It’ll be similar to what happened in 1859 when we got hit by a big solar flare.”
